Plants with various medicinal properties have been source of attraction for many scientists all over the world since thousands of years. Millions of plants have been studied extensively since ancient times for various antioxidants and their possible medicinal uses in various disease conditions in human beings. Phenolic compounds are widely distributed in the plant kingdom. Presence of phenols is considered to be potentially toxic to the growth and development of pathogen. Antioxidants are substances neutralizing the free radicals and prevent them from causing cell damage and also inhibit or prevent the oxidation of oxidizable materials by scavenging free radicals and diminishing oxidative stress. Anti-microbial agents are undeniably one of the most important therapeutic discoveries of the 20th century. Cassava (Manihot esculenta) is a perennial shrub of the Euphorbiaceous family, cultivated mainly for its fleshy tuberous roots, and is one of the most important sources of food energy and industrial raw materials in tropical and subtropical regions. The present study mainly focuses on the total phenolic, antioxidant and antimicrobial properties of Manihot esculenta leaves. The results showed that the phenolic compounds present in the leaves may contributed to the antioxidant and antimicrobial activity of cassava.
